Linux 安裝 GNOME 透過 yum下載套件

1. At first we need to install X Windows components, to do that hit the following command in shell by root user credentials,
   
   [root@hostname`]# yum groupinstall -y "X Window System"
   You will see following similar screen,
2. Now we can download and install GNOME desktop. To do so, hit the following commands,
   [root@hostname`]# yum groupinstall -y "Desktop"
3. As of now the server is running in CLI mode. So we need to configure the setting to start the server in GUI mode. To do that edit /etc/inittab file.
   [root@hostname`]# vi /etc/inittab
   Here change,
   id:3:initdefault:
   To
   id:5:initdefault:
   /* 第三步可有可無，指的是開機預設是畫面 3=command 5=GUI */
4. Download and install the fonts for GUI.
   [root@hostname`]# yum groupinstall -y fonts
5. You can now start the GUI from CLI,
   [root@hostname`]# startx
6. You can switch back between GUI and CLI.
   
   CLI to GUI : Ctrl + Alt + F1
   GUI to CLI : Ctrl + Alt + F6
   You have now have successfully installed GNOME GUI. Restart the server and you will have GUI on your screen.
